two interior feathers of the latter ; thighs white ; bill black; feet 
dark brown. 
Young. Above blue-black, but not so rich or so glossy as in 
the adult; quills and tail dusky brown, with scarcely any percepti- 
ble gloss on the upper surface ; lower part of the back pale rufous ; 
throat, cheeks, and under wing-coverts pure white; sides of the 
neck and breast rufous, but not so rich as in the adult ; under tail- 
coverts rufous, the basal half of the two interior feathers black. 
Hab. Angola, Massangano and Cambambe (Monteiro); Biballa 
(Anchieta) ; Ambaca (Anchieta) ; Damara-land (Andersson) ; Zam- 
besi (Kirk). 
This fine species was first discovered by Mr. Monteiro in Angola, 
and would seem to be by no means uncommon in Damara-land, whence 
several specimens were sent to Europe by the late Mr. C. J. An- 
dersson, principally from the vicinity of Elephant Vley in that 
country. © It has since been procured by Dr. Kirk in the Zambesi ; 
and the description given above of the young bird is taken from a 
specimen sent home by him, and now in Lord Walden’s collection.
